It is here, at an altitude of 1,589m/3,926ft that the three glacial valleys of the Impradine, the Falgoux and the Rhue meet; it is also the site of the highest road pass in the Massif Central, forming a strange knot of roads that seem to snake through the sky. In the foreground is the wooded crater of the Falgoux, dominated by the Hozière rock.
